RECORDING ATTACHMENT FOR SCALES.

' To all whomz't may concern:

to the scale proper.

Be it known that I, RENNIE E. HART, a citizen of the United States, residing at Flushin in the county of G-Ienesee and State 0 Michigan, have invented new and useful Improvements in Recording Attachments for Scales, of which the following is a specification.

My invention relates to printing devices and more particularly to a recording apparatus for use in combination with scales of difierent types which attachment is in the form of printing devices automatically operated through the movement of certain apparatus worked in connection with the scale.

A primary object'of my invention is to provide a printing attachment for plat-form scales which may be caused to. record on an invoice, bill of ladin or anything of like nature the exact-weig tof the goods on the scale, the recording. action being operated through theprinting attachment before referred to which is automatically controlled by manually operating means after the scale has been balanced.

Another object of my invention is to provide such an apparatus which shall be eff .cientin operation, simple in construction,

and convenient in its location with relation A still-further object of my invention is to provide novel means for operating the recording apparatus, said operating means being controlled bythe position of the weights on the scale and arms which latter are automatically locked through the operation of said means.

Another object is to provide operating means for the recording apparatus which shall be controlled by arms or equivalent devices yieldingly connected to the weights and positions of said arms determining of.

course the figures printed by the recording apparatus.

With the foregoing and other objects in view myinvention consists in such details of construction and arrangement of parts as will be hereinafter more fully described and specifically pointed out in the appended claims.-,

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views and in which;

. It will of course be understood that in reducing my invention to practice any suitable type or make of scale can be used. This forms no partof my invention and there.- fore has not been illustrated. The invention under construction is more in the nature of an attachment for types ofscales already in use and well known in the art. It is essential of couise that the scale to which it is to be applied be provided with the usual type of beam 1 and suspended in the usual manner from the arm 2 of the scale proper. If desired a suitable frame work for my device may be constructed such for instance as that provided by the horizontal member 3, vertical members t and 5 and so on. It

will be' again understood however that this is immaterial and forms no particular part of the invention in question. All that is essential in this connection is that the framework adapted to contain the apparatus hereinafter to be described and to be disposed in the general position illustrated in Figs. '1 and 2 and 3 of the drawings be provided. It is also essential that this framework of whatever construction it may be, be formed with a suitable table or shelf 6 conveniently located, the advantages of which will be more clearly brought out hereaften.

The scale beam illustrated and already designated by the numeral 1 is provided with three weight arms 78 and'9 respectively. The first of these may be termed the tens arm, the second the hundreds arm and the third the thousands arm, which of course are provided with the usual slidable weight 7,8 and 9 respectively. My invention may be modified and adapted for use with scales having only one weight arm or two such arms or more than three, should it be necessary, it having been illustrated in connection With the triple arm merely as an example and in order to clearly illustrate the operation of the device. On the rear sides of the Weights 7 8 and 9 are formed brackets to which are pivotally connected arms 10-11 and 12 which are normally held in an upwardly inclined position by means of springs 13 of any suitable nature.

Running crosswise of the framework before spoken of and disposed below and to the rear of the arms 1011 and 12, are slot bars 14=15 and 16 respectively, arranged-in step formation, the lowest one being below the arm 10 the middle beneath the arm 11, and the upper one below the arm 12 and out of engagement with said arms when the latter are in their normal positions. As before mentioned the bars 14-45 and 16 are provided'with slots designated by the numeral 17 which slots correspond in number and position with the units on the scale arm with which they cooperate. For instance there is a slot on the rod 14 opposite each pound marked on the scale arm 7. The rod 15 is provided with a slot opposite each hundred marked on the arm 8 and the same is also true with regard to the rod 16, its slots are formed opposite each thousand marked on the arm 9. The fact will be appreciated that if it is desired to record units smaller than pounds the number of slots on the rod 14 will have to be increased. For instance if it is desired to record one-half pounds there will have to be a slot opposite eachpne half pound graduation on the scale arm 7. .A correspondingly increased number of slots would have to be provided for one-quarter pound or smaller z'units if it should be desired that such smaller'unitsbe recorded.

Disposed to the rear of each of the rods 1415 and 16 and with their-upper ends slightly belowthe-upper edge of said rods' are rows of vertical reciprocal plungers 118-19 and 20. a The upperends of these plunger members are-each a little in the rear of the slots under. the bars before referred to and there-are as many such plunger memthe framework above spoken of are shafts 22*23 and 24 suitably journaled. Said shafts are each provided with a series of projected pins and each pin on each shaft is disposed a little beneath the lower most end of the corresponding plunger. When therefore any other plunger on the, rows 1819 and 20 are depressed the resultwill be that the pin corresponding to the depressed plungers will be enga ed and said pin will in turn rotate the shaft to which it is connected. The degree of rotation of the various shafts will be determined by the angle which the various pins make with their respective shafts as well as the length of thevarious plunger members which con struction will have the result hereinafter again referred to.

Attention has already been directed to the fact that the arms 1011 and 12 are'adapted to enter the various slots in the bars 14@-15 and 16 respectively. From whathas since been said it will be seen that when said arms enter such slots the ends of the arms will engage the plunger corresponding to the slot behind which 1t is disposed and the movement above mentioned will result. In

,order that the various arms entcrthe slots suitable mechanism accomplishing this urpose may be employed. In the drawings have been illustrated a series of'pivotally mounted bars 2526 and 27 respect vely disposed between the arms 10--11 and 12.

These bars are normally held out of engagement with the arms by means of springs as illustrated but it will be seen that upon their being moved on their pivots they will engage the arms and depress the same into the slots referred to as illustrated in Fig. 9. This operation may also be accomplished in any desired way one method beingdescribed in the drawings in which I show a hand lever 28 pivoted to the side of the part of the framework and having connection with a vertically disposed pitman 29. The lower endof the member 29 may be connected by means of a pin 30 passing through an opening in the member 41 of the framework with the lever 31 which is pivotally connected to" reds 14-;15 and 16 respectively and by the same movement to depress the corresponding plungers and operate the shafts 2223 and 24 accordingly.

The printing or recording mechanism is disposed beneath. the table or shelf 6 above referred to the actual printing being done from a series of. wheels 33-3435 and36 which are freely mounted on the shaft 37 suitably supported so as to cause said wheels to register with an opening 6 in said table. The wheels 33 and 34 are connected together so as to make it impossible for them to rotate independently of each other. The wheels 35 and 36 have no connection with 33 and 34 or with each other each being independently mounted. The first two referred to carry the tens and units, and correspond with the Weight arm I and the scale beam. The wheel 35 carries the hundreds and correspondswith the arm 8, and the wheel 36 carries the thousands and corresponds with the arm 9. Suitable means are provided for holding all of these wheels in their normal positions. It would probably be found advisable todo this by three weights sus pended from hubs of the wheels as is illustrated in detail from Fig. 6. Because of the large number of numerals carried by the wheels 33 and 34 it would probably be necessary for these to rotate an entire revolution, whereas the others carrying a comparatively small number of numerals would probably not have to rotate at any time more than about one-tenth of a revolution, The method of holding them intheir normal positions is perfectly adapted to these conditions. As soon'as the weight 38 is suspended from the hub between the wheels 33 and 34 it will be wound upon said hub as well as rotate. The weight 39 is suspended from the hub of the wheel 35 and the weight 40 from thehub of the wheel 36 and will operate in a similar manner.

Any suitable connection may be made hetween,the wheel's 33 '34-35 and 36 and the shafts 22 2324 whereby said wheels may be suitably revolved when said shafts are operated as in the manner above described at length. One way in which this can be done is illustrated in Figs. 4-7 and 8 of the drawings. 'Here is shown the shafts referred to provided with hubs 4-142 and 4-3 around which are partly wound tapes ii-- 45 and-4-6 respectively. The other ends of these tapes are similarly wound around hubs connected to "the several wheels as for instance around the hub 47. As a consequence of this construction the rotation or partial rotation of any of the shafts 2223 and 24 by means before set. forth willcause a corresponding movement of the wheels 3334 and and 36. This will bring the desired numerals in rotation with the opening 6' inthe table 6.. Above this opening or adjacent. thereto may be disposed a stamping mechanism 48 of the well known type, as this forms no part of my invention it has not been illustrated in detail.

It is thought that the construction and operation of the invention in question will be apparent from the foregoing description. It will be seen that first of all the scale beam isbalanced in the usual way. When the same is balanced the hand lever 28 is depressed Which through the operation before described rotates the shafts which in.turn partially rotate the printing Wheels bringing the numerals corresponding with the weight of the goods exactly beneath the opening. 6'. The bill of lading, invoice or any similar form may be placed over said opening and the stamping apparatus incidentally referred to above is operated to stamp the exact weight thereon. This obviates the necessity of writing on the weight in pencil and avoids the chance of error incident to such a procedure. It saves considerable time, trouble and inconvenience and absolutely assures accuracy.

I desire it to be understood that my invention as described above cannot be con-- sidered as perfected in its details, all I claim at the present time being the principles involved in its operation. Changes may be made without departing from the spirit of my invention provided such changes fall within scope of the appended claims.
